BOTTLE-TAP.

ings, of which- Figure 1 is a side elevation of a'bottle with one of my improved taps applied to it. Fig.

2 is a side View, and Fig. 3 a vertical and longitudinal section, of the tap separate from the bottle. d

This tap is to enable the liquid contents of the bottle to be expelled therefrom through an educt by means of air forced into the bottle. In some respects the tap is analogous to that for effecting the discharge of the liquid contents of a bottle by pressure on the liquid of carbonic-acid gas generated in such contents by fermentation thereof.

The nature of my invention is defined in the claim hereinafter presented.

In Fig. 1 of the drawings, A represents a bottle having the tubular corkscrew D of the tap B screwed into and down through the cork O of such bottle, the said tap having a pipe, a, to extend and slide through the tubular corkscrew D down into the bottle nearly to its bottom. The said pipe a has to the upper part of its bore 9 a stop-cock, E, and a nozzle, F, the latter extending from the stopcock in manner as represented.

which is entirely distinct from the bore of said corkscrew. This passage is made vertically in the corkscrew alongside of said bore,

and runs from the lower end of the corkscrew up into the head B of the same, at whichpoint it is connected with a transverse passage, 1), in such head. This head is connected by a suitable coupling with an elastic air-forcing the corkscrew the tap can be adapted to bot- The corkscrew D is formed with an airassa 'e b the cork.

the bore the entire length of the tap, the con 100 it is customary to insert loosely in the tube a, atits lower end, a metallic point that will easily fall out of the pipe on the passage of it through the cork. Having done this and forced the pipe and point down through the cork until the corkscrew may have reached the said cork, such corkscrew is to be revolved, so as to screw it closely down into and through the cork. The bulb should be next alternately compressed by hand and allowed to expand, whereby air will be forced into the bottle and compressed therein. On opening the stopcock the elastic force of the compressed air in the bottle will drive the liquid thereof through the pipe to and the stop-cock and nozzle. The said nozzle is a convenient auxiliary to the stopcock, and may be curved or formed as occasion may require.

By having the pipe to to slide tightly through tles of different heights, the pipe a, after having'been inserted, being pressed down nearly to the bottom of the bottle.

With my invention adapted to a bottle the latter may be kept securely closed when it may not be desirable to extract from it any of its liquid contents, and the liquid may be expelled from it as occasion may require.

I am aware that a bottle-tap has been devised provided with an exterior thread and an interior bore, through which bore passes an eduction-pipe having a cock at its upper end, the said bore being larger than the pipe, and having a tube leading within, so that air may be forced through the bore into the bottle and the contents of the latter up the pipe. In my devicethe eduction-pipe fits tightly the bore of the tap through which it passes, there being no space whatever around the pipe in the tap. The air is forced into the bottle through a pas sage which passes down the tap, entirely disconnected from the bore 0r passage in which the eductionpipe operates. By having a dis tinct passage for the air alone, such passage is always kept free and clear, no accumulation from the contents of the bottle can be drawn therein, nor 'willpieces of the cork become jammed therein in pushing the tap through As the eduction-pipe tightly fits tinet air-passage, in combination with on eduo1- talon-pipe passing through and (closely fitting I0 such bore as set forth.

neotion between the two is completely airseuled; hence the bottle can be filled with compressed air and kept in that condition indefinitely, as there is no danger of the air es- 5 coping.
